RRC state indicates whether the rrc layer of UE is logically connected to the rrc layer of E-UTRAN.RRC state can be divided
Into such as RRC idle conditions (RRC_IDLE) and two kinds of different states of RRC connection status (RRC_CONNECTED).
Under RRC_IDLE, UE can be with the broadcast of reception system information and paging information, while UE specifies the discontinuous reception configured by NAS
(DRX) mark (ID) of UE, and during UE has been dispensed on tracing area is uniquely identified, and public land can be performed
Mobile network (PLMN) selects and cell reselection.Additionally, in RRC_IDLE, RRC contexts are not stored in the enb.
Under RRC_CONNECTED, UE has E-UTRAN RRC connections and context in E-UTRAN so as to eNB
Send data and/or receive data from eNB and become possibility.Additionally, UE can be to eNB reporting channel quality informations and feedback letter
Breath.Under RRC_CONNECTED, E-UTRAN knows the cell belonging to UE.Therefore, network can to UE send data and/or from
UE receives data, and network can control the mobility of UE (to switch and use network assisted cell change (NACC) to GSM
Cell change order between the radio access technologies (RAT) of EDGE radio access networks (GERAN)), and network can enter
Cell measurement of the row for neighbor cell.
Under RRC_IDEL, UE specifies paging DRX cycle.Specifically, UE is in the specific of the specific paging DRX cycles of each UE
Paging occasion monitors paging signal.Paging occasion is the time interval that paging signal is sent during it.UE has its own
Paging occasion.Beep-page message is sent in all cells for belonging to identical tracing area.If UE is from a tracing area
(TA) another TA is moved to, then UE sends tracking area update (TAU) message to update its position to network.
Description is based on close service (ProSe)." ProSe " can be used in mixed way with " D2D ".
ProSe direct communications it is meant that by via not across the path of any network node using E-UTRAN technologies
User-plane transmissions, the communication between two or more the close UE for enabling ProSe.The UE for enabling ProSe means
Support the UE of ProSe demands and associated process.Unless expressly stated otherwise, the UE for otherwise enabling ProSe refers to non-public affairs

In order to send data under CONNECTED.UE asks transfer resource from eNB.ENB dispatches the transmission for scheduling assignment and data
Transfer resource.UE follows hard on ProSe BSR and sends dispatch request to eNB (special dispatch request (D-SR) connects at random
Enter).Based on BSR, eNB can determine that UE has the data for the transmission of ProSe direct communications and estimates for needed for transmission
The resource wanted.In mode 2, UE selects resource to send scheduling assignment and data from principal and subordinate's resource pool.
If UE has Serving cell, and (that is, UE is under RRC_CONNECTED or resides under RRC_IDLE
Cell), then it is assumed that it is in covering.If UE is outer in covering, it only being capable of use pattern 2.If UE is in covering, if
ENB is correspondingly configured to it, then it can be with use pattern 2.When in the absence of exception, only when configuring its this by eNB
When doing, pattern 1 is just changed to become the mode and 2 or changes pattern 2 and become the mode 1 by UE.If UE is in covering, unless exception feelings
A generation in condition, otherwise it will be using only the pattern indicated by eNB configurations.When T311 or T301 are currently running,
UE considers that its own is in exception.When exception occurs, it is allowed to UE provisionally use pattern 2, although it is matched somebody with somebody
It is set to use pattern 1.
It is populated or is connected to a carrier frequency but in another carrier frequency to ProSe direct communication operation senses
The UE of interest will attempt finding cell in ProSe carrier frequencies.Once it detects appropriate cell, another load is resided in
The UE of the cell in wave frequency rate, but the RRC_IDLE in the overlay area of the E-UTRAN cells in ProSe carrier frequencies, can
With gravity treatment ProSe carrier frequencies.When it wishes to carry out ProSe communicates, by the RRC_ of the cell serves in another carrier frequency
CONNECTED UE indicate ProSe direct communications to be sent to its Serving cell.Indicate comprising the ProSe carrier frequencies wanted
Rate.Serving cell provided for radio resources management (RRM) can be measured between configuration frequency in ProSe carrier frequencies, once and UE
Into the covering of cell in ProSe carrier frequencies, then moved between the frequency of ProSe carrier frequencies is triggered to based on measurement report
It is dynamic.If UE detects cell in ProSe carrier frequencies, and if via SIB or dedicated signaling straight for ProSe
The E-UTRAN connected in the ProSe carrier frequencies of letter does not provide the resource in ProSe carrier frequencies, then UE will not be used
For the ProSe resources that the frequency is pre-configured with.If UE does not find E-UTRAN cells, UE energy in ProSe carrier frequencies
It is enough to use the ProSe carrier frequency resources being pre-configured with for pattern 2.
For the UE under RRC_IDLE, eNB can in system information block (SIB) the transfer resource pond of offer pattern 2.
Under RRC_IDLE, the UE being authorized to for ProSe uses these for the resource of ProSe direct communications.Alternatively, eNB
It can be indicated but ProSe direct communications are supported not for it provides resource in SIB.UE needs to enter RRC_CONNECTED
To perform the transmission of ProSe direct communications.
For the UE under RRC_CONNECTED, be authorized to perform the transmission of ProSe direct communications in RRC_
UE under CONNECTED indicates it to wish to carry out the transmission of ProSe direct communications to eNB.ENB is used from the UE that MME is received
Hereafter come verify the UE under RRC_CONNECTED whether for ProSe direct communications transmission be authorized to.ENB can pass through
UE of the dedicated signaling configuration with the resource allocation transfer resource pond of pattern 2 under RRC_CONNECTED, the resource pool is in UE
Can be used without limitation when under RRC_CONNECTED.Alternatively, eNB can be by with the resource of pattern 2 point
Dedicated signaling configuration with transfer resource pond is in the UE under RRC_CONNECTED, and UE is only allowed to use in exceptional cases
The resource pool, and otherwise depend on pattern 1.
For receive and send can be pre-configured with when UE cover it is outer when for scheduling assignment resource pool.Can be as follows
Configuration is when UE is in covering for the resource pool of scheduling assignment.Via RRC, with special or broadcast signaling, configured by eNB
For the resource pool for receiving.If the resource allocation of use pattern 2, via the resource pool that RRC is configured to send by eNB.
If the resource allocation of use pattern 1, the SA resource pools for sending are unknown for UE.If the resource of use pattern 1 point
Match somebody with somebody, then eNB schedule specific resources send for scheduling assignment.Specific resources from eNB assignments are in the tune for being provided to UE
In the resource pool of the reception for spending assignment.
Even if in order to when some UE are in covering and some UE perform communication when covering outer, all UE (that is, are covering
It is outer that lid neutralizes covering) should monitor resource pool for scheduling assignment, the resource pool is (or as in covering for owning
The union of the resource pool of the transmission of the scheduling assignment in cell and the transmission of the scheduling assignment outside covering a bit).
ProSe directly has found the process for being defined as being used by the UE for enabling ProSe, and the process is direct using E-UTRAN
Radio signal is found in its close other UE for enabling ProSe via PC5.The branch only when UE is serviced by E-UTRAN
ProSe is held directly to find.
Fig. 7 shows the example of the PC5 interfaces directly found for ProSe.With reference to Fig. 7, UE A and UE B are assisted using ProSe
View performs ProSe and directly finds via PC5.Upper strata processes the mandate of notice and the monitoring for finding information.It was found that information
Content is that the type for finding that model and ProSe directly have found transparent and direct for ProSe is not carried out for AS
Differentiation in AS.ProSe agreements ensure that it only transmits effective discovery information to the AS for noticing.UE can be according to eNB
The notice and monitoring of discovery information are participated under RRC_IDLE the and RRC_CONNECTED states of configuration.UE is noticed and is monitored it and receives
The discovery information of half-duplex limitation.Notice and monitoring UE maintain current (UTC) time Coordinated Universal Time(UTC).Notice UE is having found message
Transmission when send in view of UTC time by ProSe protocol generations discovery message.Monitor UE in, ProSe agreements to
ProSe functions provide the message that be verified together with UTC time in the reception of information.
The radio protocol stack (AS) directly found for ProSe is only made up of MAC and PHY.AS layers performs and upper strata
The interface of (ProSe agreements).MAC layer receives discovery information from upper strata (ProSe agreements).IP layers not be used to send discovery letter
Breath.AS layers also performs scheduling.MAC layer determines to be used for the radio resource of the discovery information that notice is received from upper strata.AS
Layer is also performed and finds PDU generations.MAC layer build carry discovery information MAC PDU and to for it is determined that radio provide
The physical layer of the transmission in source sends MAC PDU.Without MAC header.
In the presence of two kinds of types for finding the resource allocation of information announcement, it includes Class1 and type 2.Class1 resource
Distribution is the resource allocation process of the resource that the notice for finding information is distributed on the basis of non-UE is specific.In Class1,
ENB provides the resource pool configuration of the notice for finding information to UE.Can be with SIB signal send configurations.UE from indicate
Resource pool voluntarily selects radio resource and notices discovery information.UE can be noticed on random during each discovery period
The discovery information of the discovery resource of ground selection.The resource allocation of type 2 is distributed for finding information on the basis of UE is specific
The resource allocation process of the resource of notice.In type 2, the UE under RRC_CONNECTED can be asked via RRC from eNB
Seek the resource of the notice for finding information.ENB is via RRC assigned resources.In the resource pool for monitoring configured in UE
Distribution resource.
For the UE under RRC_IDLE, eNB can provide the Class1 resource for finding information announcement in SIB
Pond.Directly find that the UE for authorizing is used to notice the resource of discovery information under RRC_IDL using these for ProSe.Alternatively,
ENB can indicate it to support that but ProSe directly has found does not provide the resource for finding information announcement in SIB.UE needs
Into RRC_CONNECTED in order to ask the resource for finding information announcement.
For the UE under RRC_CONNECTED, it is authorized to and performs the UE that ProSe directly has found notice, when its needs
When execution ProSe directly has found notice, indicate it to wish to carry out ProSe to eNB and directly find notice.ENB is used and received from MME
To UE context validations UE whether for ProSe directly find notice and be authorized to.ENB can be via special RRC signaling
(or No Assets) configure UE with using for finding the Class1 resource pool or the resource of private type 2 of information announcement.By
The resource of eNB distribution is effective, and until a) eNB, by RRC signaling de-provision resource or b) UE enters RRC_IDLE.
The Class1 and type 2 that reception UE monitorings under RRC_IDLE and RRC_CONNECTED are authorized to find resource
Both ponds.The resource pool that eNB provides for finding information monitoring in SIB is configured.SIB can also be comprising in neighbor cell
The discovery resource of middle notice.
Support synchronous and asynchronous deployment.It was found that resource can be across small area overlapping or non-overlapped.Serving cell can be in SIB
It is middle that the information that adjacent frequency supports ProSe directly to find is provided.Disposed in order to synchronization, full weight are folded, in frequency, eNB is only provided
One resource pool (it is required that non-D2D synchronizing signals (D2DSS) information).
If by network authorization, UE only can on the serving cell declare that ProSe directly has found information.UE can be
It is middle between frequency and between frequency and between PLMN in frequency to monitor the discovery resource in PLMN.Serving cell can be carried in SIB
The list (there may be corresponding PLMN ID) of the frequency that ProSe directly has found information can be intended to monitor for UE thereon.
Serving cell does not provide the detailed ProSe discovery configurations for other carrier frequencies.If UE is wanted on these carrier waves
Perform ProSe and directly find infomation detection, then it will read SIB SIB 18 relevant with other on other carrier waves.It is logical
The SIB18 (and other SIB) of between crossing reading frequency and/or PLMN minizones obtains ProSe and finds that configuration should not be influenceed in clothes
The Uu of the UE in business cell is received.ProSe in frequency, between frequency and between PLMN directly has found that monitoring should not influence Uu to receive.
If it can be used in frequency, the ProSe between frequency and between PLMN directly has found infomation detection, UE in RRC_IDLE and
DRX occasion is used in RRC_CONNECTED or the second reception chain.UE will not create spontaneous gap.If in frequency,
ProSe has found that information monitoring is interesting or no longer interested between frequency or between PLMN, then RRC_CONNECTED UE will
ProSe has found that instruction is sent to Serving cell.
Group communication system enabler (GCSE) (including MBMS features) and D2D communications can be primarily used to public peace
Entirely.Therefore, it can exist while UE receives MBMS in Multicast Broadcast Single Frequency Network (MBSFN) subframe and may wish to connect
Receive the situation (for example, being particularly used for public safety service) in D2D communication resources pond.Furthermore, it is possible to there is UE in MBSFN sub-frame
May wish to monitor the situation (for example, for commerce services) that D2D has found resource pool while upper reception MBMS.
The support received while D2D resources and MBMS resources can come into question under two kinds of scenes, and one is identical
Cell on provide D2D resources and MBMS resources, and another be in different cells provide D2D resources and MBMS money
Source.
For the first scene of D2D resources and MBMS resources is provided wherein in identical cell, it is possible to, branch
The UE for holding D2D can simultaneously receive both DL resources and UL resources in cell.Therefore, if this UE is also in the DL frequencies of cell
Support that MBMS is received, then UE can support that the D2D resources in the UL frequencies of cell and the MBMS in the UL frequencies of cell are provided
Received while both sources, i.e. for identical cell.It is well known that MBMS enables UE supporting on main plot (PCell)
MBMS is received as basic MBMS abilities.However, the MBMS in secondary cell (SCell) is received and on non-service cell
MBMS is received and is limited by UE abilities.Therefore, the support pair for being received according to the MBMS on PCell, SCell and non-service cell
The support received while both D2D resources and MBMS resources at identical cell can be at least following different.
(1) if UE supports that D2D operations and MBMS receive both, UE should support that D2D resources and MBMS on PCell are provided
Received while both sources.
(2) if UE supports that the MBMS on SCell is received and the D2D on identical SCell is received, UE should be supported
Received while both D2D resources and MBMS resources on identical SCell.
(3) if UE supports that the MBMS on non-service cell is received and the D2D operations on identical non-service cell,
Then UE should support to be received while both D2D resources and MBMS resources on identical non-service cell.
For the second scene of D2D resources and MBMS resources is provided wherein in different cells, network may be
D2D resources and MBMS resources are provided in different frequencies at different cells.For example, when UE may reside within frequency 1
When in first community, network can provide MBMS in frequency 2 at second community, but small the 3rd in frequency 3
D2D resources are provided at area.In this case, it is same for both D2D resources and MBMS resources in different cells
When the support that receives be likely to be dependent on whether UE support these cells frequency combination.Unfortunately, do not completely address
The problem of the UE ability relevant for D2D.Therefore, when the UE ability relevant with D2D is made apparent from, if UE can be not
Receive and should be discussed further while support both D2D resources and MBMS resources at different cells in same frequency.
But, it appeared that there are particular UE does not support that D2D resources and MBMS are provided at different cells over different frequencies
Situation about being received while both sources.For example, depending on UE abilities, the UE for residing in the first community in frequency 1 can be in frequency
The reception of MBMS resources is supported at rate 2, but the reception of D2D resources can not be supported at the 3rd cell in frequency 3.Or
Person, residing in the UE in the first community in frequency can not support the reception of MBMS resources at frequency 2, but can be to support
The reception of D2D resources.
In order to solve problem described above, if can propose that UE can not be simultaneously according to an embodiment of the invention
Support that MBMS is received and D2D receives both and is then prioritized MBMS and receives or the method for during D2D is received.According to the present invention
Embodiment, UE can be selected between different frequencies D2D receive or MBMS receive in one because UE can not be supported
Receive simultaneously.If UE receives D2D received prior to MBMS, possible UE shifts to the frequency for providing D2D resources.If UE makes
MBMS is received and received prior to D2D, then possible UE shifts to the frequency for providing MBMS resources.This UE behaviors may connect with MBMS is made
Receive similar prior to unicast reception.Therefore, when in RRC_IDLE, if receive MBMS received prior to D2D, UE can be with
MBMS frequencies are prioritized according to MBMS continuity Characteristics.Otherwise, UE can not be prioritized MBMS frequencies in cell reselection.
That is, if UE can not support to be received while both D2D resources and MBMS resources on different carrier waves, and if make
D2D operator precedences are received in MBMS, then the UE in RRC_IDLE is not prioritized when D2D receptions are performed in cell reselection
MBMS frequencies.
In addition, when in RRC_CONNECTED, UE can have providing to be received with MBMS receptions and D2D to network
MBMS is indicated to receive in MBMSInterestIndication message or in new ProSe instruction message during the UE abilities of pass
Received prior to D2D.Therefore, eNB can be suitably configured to the Serving cell that MBMS is received or D2D is received.For example, working as
When in RRC_CONNECTED, if receive MBMS received prior to D2D, eNB can be according to relevant with MBMS receptions
UE abilities configure PCell or SCell in MBMS frequencies.Otherwise, eNB can be received in ProSe carrier frequencies for D2D
Configuration service cell.UE can have for D2D communication and D2D find different MBMS priority because D2D communication and
The service condition that D2D has found can be different.Additionally, for example, a UE is generally used as commercial use so that it can
So that GCSE/MBMS is received prior to D2D communications.But, this UE may wish to make D2D find to be received prior to MBMS, because
They want to see neighbouring neighbouring discovery declaration.On the other hand, another UE can by normally be used as safety applications and
It is talkative (for example, leader of group) so that it can make D2D communicate prior to MBMS receptions.But, this UE may wish to make
MBMS is received and found prior to D2D.
In the following, it is described that according to various embodiments of the present invention.

The result to be prioritized is incorporated as, then UE can indicate emerging to ProSe carrier frequency senses with (indicating message via ProSe) to network
Interest.Alternatively, if MBMS is received is received result as priorization prior to D2D, UE can be (referring to via ProSe
Show message) indicate to lose interest in ProSe carrier frequencies to network.In this case, indicate to can correspond to not include
The ProSe of " ProSe carrier frequencies " indicates message.
For the fourth embodiment of the present invention, if UE can not simultaneously support that MBMS is received and D2D is received, to receive
MBMS transmission or the UE of D2D transmission can be such that MBMS receives prior to D2D receptions or D2D receptions is connect prior to MBMS
Receive.D2D receives the reception of the reception or D2D discovery declarations that can correspond to D2D communications.If additionally, MBMS is received into excellent
The result as priorization is received prior to D2D, then the MBMS frequencies for providing MBMS interested can be considered as highest by UE
Cell reselection priority.Alternatively, received prior to MBMS if D2D is received, UE will can not provide interested
The MBMS frequencies of MBMS are considered as highest cell reselection priority.
Fig. 8 show to be prioritized according to an embodiment of the invention MBMS receive or during D2D is received example.
In the step s 100, if UE can not simultaneously support that MBMS is received and D2D receives both, UE is prioritized MBMS
One in reception or D2D receptions.D2D receives the reception of the reception or D2D discovery declarations that can correspond to D2D communications.
